I am currently trying to implement a cache coherence protocol where I need to store current global timestamp … WebGem5 has multiple implemented replacement policies. Each one uses its specific replacement data to determine a replacement victim on evictions. All of the replacement policies prioritize victimizing invalid blocks. A replacement policy consists of a reset (), touch (), invalidate () and getVictim () methods. WebYou can download the Second Edition via this link.

The L1 cache is private to a core, while the L2 cache is shared among the cores. L1 Cache is split into Instruction and Data cache. Inclusion is maintained between the L1 and L2 cache. At high level the protocol has four stable states, M, E , S and I.

GEMS used Ruby as its cache model, whereas the classic caches came from the m5 codebase (hence “classic”). The difference between these two models is that Ruby is designed to model cache coherence in detail. Part of Ruby is SLICC, a language for defining cache coherence protocols.
